Methods of increasing the rate of lactic acid permeation in skin for the treatment of dermatological disorders by applying a composition containing an inorganic or organic salt of lactic acid in a dermatologically acceptable composition wherein at least 70% of the lactic acid moiety in the salt is L-lactic acid, and compositions for practicing such methods.

A compartmentalized container of rectangular-like shape consisting of a lower and upper portion each of which contains at least one compartment for receiving material such as refuse. The upper and lower compartments are accessed by operation of pedals operating on the top lid of the container and the lower front panel of the container respectively. This allows hands-free use of all the compartments for segregating refuse into reusable or recyclable components, such as bottles, papers, or cans. The container is designed to use surplus grocery and shopping bags in addition to normal garbage bags in the containment and disposal process.

The solubility of tissue plasminogen activator in aqueous solution is enhanced by incorporating therein arginine or a non-toxic salt of arginine in an amount effective to increase the solubility of the t-PA without substantially inhibiting its potential biological activity upon administration.
